Basics
All Index types support the same operators. Using the following Index3 definitions, the
results of the various operations are listed.
int i1 = 3;
int j1 = 5;
int k1 = 7;
int i2 = 9;
int j2 = 13;
int k2 = 17;
Index3 idx_1 = new Index3(i1, j1, k1);
// Value for idx_1 is (3, 5, 7)
Index3 idx_2 = new Index3(i2, j2, k2);
// Value for idx_2 is (9, 13, 17)
+ (addition)
Index3 idx_add_idx = idx_1 + idx_2;
// Value for idx_add_idx is (12, 18, 24) from 3+9, 5+13, 7+17
Index3 idx_add_int = idx_1 + 5;
// Value for idx_add_int is (8, 10, 12) from 3+5, 5+5, 7+5
Index3 int_add_idx = 5 + idx_1;
// Value for idx_add_int is (8, 10, 12) from 5+3, 5+5, 5+7
- (subtraction)
Index3 idx_sub_idx = idx_1 - idx_2;
// Value for idx_sub_idx is (-6, -8, -10) from 3-9, 5-13, 7-17
Index3 idx_sub_int = idx_1 – 5;
// Value for idx_sub_int is (-2, 0, 2) from 3-5, 5-5, 7-5
Index3 int_sub_idx = 5 – idx_1;
// Value for int_sub_idx is (2, 0, -2) from 5-3, 5-5, 5-7
Index3 sub_idx = -idx_1;
// Value for sub_idx is (-3, -5, -7) from -1*3, -1*5, -1*7
